Commentary:

The story associated with this
verse and the following one (DhP 27) speaks about a festival that was celebrated
in the city of Sāvatthī while the Buddha was residing there. Many young men were practicing some sort of religious rituals,
roaming about the city, shouting and begging for money at every door in the
city. Buddha's lay disciples in that city warned him not to enter the city
and they themselves did not leave their houses. After one week of the festival
ended, the Buddha again entered Sāvatthī and then spoke these two verses (DhP
26 and 27).
